Original application filed March 14, 1918, Serial No. 222,334. Divided and this application filed Septemher 27,1918.

To all whom it may concern:

Be it known that I, EDWARD M. HEYLMAN, a citizen of the United States, and a resident of South. Bend, in the county of St. Joseph and State of Indiana, have invented cer tain new and useful Improvements in Agricultural Implements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in agricultural implements, such as plows, and more particularly to mountings for the disks, this application being a division of application for patent filed by me on the 14th day of March 1918 and designated by Serial No. 222,334.

One object of the present invention is to so construct a disk mounting that the part which constitutes the bearing for the disk spindle shall be of such form and proportions that it will be prevented from dragging against the bank when plowing deeply.

A further object is to improvethe structure and enhance the strength and eiiiciency of the bearings of a disk plow.

With these and other objects in view, the invention consists in certain novelfeatures of construction and combinations of parts v as hereinafter set forth and pointed out in the claim. y

In the accompanying drawings; Figure 1 is a sectional view showing an embodiment of my inventionpFigure 2 is an end view of the flanged spindle; Figure 3 illustrates the washer at one end of the spindle; Figure 1 is a view of the arm or plate having the hub in which the disk spindle ismounted, and Figures 5 and 6 are views of the bushings.

1 represents a soil-engaging; disk and 2 a beam or other part of a plow structure with which the disk is connected through the medium of suitable instrumentalities.

A spindle 3 for the disk is provided with 4 an annular flange 4 which is securely fastened to the back of said disk by means of bolts 5. The spindle 3 is mounted in a hub 6 and; the latter is connected, through the medium of an arm or plate 7* (which may be integral with said hub) and attaching devices, with the be or frame member 2.

Serial No. 255,928.

The hub 6 is also made with an opening 16 to permit dirt that may work in from the top and; front,ito drop out. .1

a The spindle 3 is made large at the, portion thereof nearest the flange 4: in order to gain adequate strength at this portion or the spindle, and the rear portion of said spindle is contracted in size so that the rear end. of the bearing may be so reduced in size as to prevent the same from draggingagainst the. bank in case of deep plowing. The hub 6 has the same general shape as the spindle, and two'separate bushings 7, 8, areemployed,-the bushing 7 entop of the hub communicates The larger, l

bushing T bears at. one end against a shoulde'r 12 on the spindle and at the other end it has a thrust bearing against a flange or Mb 13 in thehub 6, while the smaller bushing 8 rests at one end against a flange 7.

or 'rib 1% in the hub and 'at theother and against I a cap disk coniing"agaiiist the'bushing member placement of the smaller bushing member 8 will be prevented when' the plow is raised, by the rib '14. A bolt 16 passes: .90

through the spindle 3 and its inner'portion is threaded to enter the threaded portion 15 screwed into the. end of thehub. Thus the, thrust of the of the bore in saidsp'indle. The outer end i of the bolt 16 is provided with a' head '17,

between which and the end oftliespindle, a

washer 18 is located. This washer overlies the bushing member 8 and is provided with lugs 19 which enter sockets 20 in the end of the spindle It will be seen that the bearing parts of thespindle at the bushings are substantially straight, and this is'an advantage over a taper construction because, if there is any end play, there will not be too much up and-down play in the bearing when. the spindle is drawn forwardly,

Having fully described my invention what I claim as new and desire to secure by Let ters-Patent, is

The combination oi a supporting member,

7 will be Tsisted y rib 13, and dis- I provided with a hub member having two portions differing in diameter, a soil engaging dish, a spindle having a central bore provided with a threaded portion and having two bearing portions difiering in diameter, bushings disposed between the hub and the respective bearing portions of the spindle and separated from each other, forming a chamber between them, said spindle having a part fixed to therear face of the disk,

a bolt in the bore of the spindle and headed at its rear end, said bolt terminating at its other end rearwardly of the disk and enlaging the threaded portion of the bore in the spindle, a disk disposed between the head of the bolt and the free end of the spindle and engaging the latter, and a cap entering said hub and enclosing the free end of the spindle and the headed end of said bolt.

In testimony whereof, I have signed this I specification in the presence of two subscribing witnesses.
